After Xia Li entered the warehouse, he found a pile of charcoal from the corner of the wall, put it in a bag, added a few handfuls of salt, and threw it on the ground.

"Slap, smack, smack, smack!" Special decompression.

Chen Wenwan, who was reading in the room, didn't know that Xia Li was back, and was immediately startled when she heard a particularly loud noise from the warehouse.

hurriedly came out to check, and saw that his roommate was like having "bipolar disorder" to vent his emotions, holding a sack and throwing it to the ground.

Chen Wenwan's footsteps were subconsciously paused, the back of the whole person was a little stiff, her body did not move, her head tilted slightly, and she pretended to look at Xia Li calmly.

"Sister, what are you doing?"

She knew that the sister must have been stimulated by going to the countryside, and it was normal if she really had any quirks.

It's just that if he smashes things like this every day in the future, will she treat it as if she didn't see it, or will she prepare more things for her to smash?

When Xia Li heard this, she turned around and saw the cold beauty standing at the door, looking at her with a complicated expression.

Xia Li glanced down at the burlap bag in his hand, and then looked up at Chen Wenwan.

"Do you want a lamp?"

Chen Wenwan heard that there was a little more brilliance in her eyes, the corners of her mouth hooked slightly, and she said unceremoniously: "Yes."

What do you need me to do? ”

Xia Li simply didn't shake it off, and handed the burlap bag in his hand to Chen Wenwan, "Grind the charcoal inside into powder." ”

Chen Wenwan didn't hesitate, and directly reached out to pick up the things.

"Okay, I'll give you a moment."

After a while, the warehouse sounded "Bang!" again. Syllable! Syllable! "A very decompressing thump.

After Xia Li assigned the work, he went to the kitchen to transfer a large basin of salt water, brought it back to his room, and closed the door tightly.

A large basin of salt water was placed on the table, and Xia Li stretched out two fingers and put them into the water, acting as positive and negative poles and starting to cast abilities.

If this was before the time travel, Xia Li never dreamed that one day he would actually use his ability to hunt the zombie king and go to a strange era to use salt water to electrolyze hypochlorous acid, just to make a few dry batteries.

A large basin of salt water bubbled up by her electricity, and soon a basin of hypochlorous acid solution was formed.

Chen Wenwan had already knocked the charcoal into powder, and when she walked outside Xia Li's room, she saw that the door was closed.

Although she gossiped, she was not an eventful character, and when she saw that Xia Li's door was not opened, she just walked to the door and knocked on the door.

He raised his voice and said, "I've finished grinding, will I put it at the door for you?" ”

Xia Li heard the sound outside the door, so he walked out with the pot of sodium hypochlorite in his arms, and raised his chin at the warehouse behind Chen Wenwan.

"Let's go there, save yourself all over the place."

Chen Wenwan didn't have any opinions, glanced at the large basin of liquid that Xia Li was holding in his arms, turned around and carried a large bag of charcoal powder into the warehouse.

The two of them looked around in the warehouse and found two bamboo tubes.

Xia Li poured the charcoal powder and hypochlorous acid solution into the bamboo tube according to the ratio of five hundred milliliters of hypochlorous acid solution of three catties of charcoal powder, and mixed it into a piece.

He took another lid and symbolically covered it.

Chen Wenwan had never seen this thing before, and was still a little puzzled, "What is this for?"

I thought you'd get a generator and put it in our yard. ”

Xia Li: "Dry battery, but soak it for four or five days first." ”

As she spoke, her expression was a little helpless, "I also want to get a generator, but the generator needs energy to operate."

Our current engine can indeed be used as power, but it is not safe to burn firewood every day, and we can't always get up in the middle of the night to add fuel to his fire.

When I woke up in the middle of the night, there was no light in the dark, and the light was useless. ”

Today's level of science and technology is not high, and it is estimated that the principle of solar energy has not yet been developed.

Otherwise, if she can get a solar panel, she can directly get a solar generator, absolutely once and for all.

Chen Wenwan didn't understand Xia Li's energy immeasurable, but she knew the battery.

Hearing that Xia Li was going to use the packet of toner just now, plus a basin of liquid that I don't know what it was, he looked at Xia Li like he was looking at a science madman who had escaped.

"You can't really be some kind of research institute that sneaked down, right?"

Xia Li: ???
